Product Description

Product Description

Introduction:

Linear shafts are steel rods made of C4140 Induction Hardened and Hard Chrome plated.The rods undergo rigorous processes like pilling, straightening, hardening, grinding, polishing, hard chrome plating and finishing under the supervision of experienced engineers. Different from the Hard Chrome Plated Piston Rods, the surface hardness of the Induction Hardened Chrome Rods is high up to HRC58-62 via high-frequency induction harden technique. Linear shafts are usually used as guide rail or slide rail matching with Linearing Bearings because of the surface high durability, abrasion resistance, longer working life and dimensional accuracy.

 

WHAT CAN WE SUPPLY :
1,We can offer full rangs of linear shafts with diameter 3mm- 120mm, maximum length up to 8000mm.
